A new study of 30-million-year-old fossil ‘mega-dung’ from extinct giant South American mammals reveals evidence of complex ecological interactions and theft of dung-beetles’ food stores by other animals.

According to one theory, severe head injury causes leaks in the blood-brain barrier that allow entry of serum albumen, which triggers epilepsy and seizures. Scientists now show that albumen interacts with the TGF-beta receptor on astrocytes, triggering a cascade of events that lead to epilepsy. In rats, TGF-beta blockers stop such changes in the brain, [...]

When a dad changes diapers and makes pediatrician’s appointments, he’s more likely to stay interested and involved when his child makes the transition to school, said a new study that explores the role of parent involvement on student achievement.
A low-cost generator with the potential to transform lives in the world’s poorest communities is now being tested across the UK and in Nepal. Researchers are developing a bio-mass burning cooking stove which also converts heat into acoustic energy and then into electricity, all in one unit.
Selenium is a trace element crucial to life — too little or too much of it is fatal. Scientists now detail the molecular mechanisms that govern its metabolism in the human body.

The molecular machinery that helps brain cells migrate to their correct place in the developing brain has been identified. Understanding how neurons migrate to their proper place during brain development will offer insights into how malfunctions in the machinery cause epilepsy and mental retardation.
